Along with acoustic spray foam applied in 14 critical locations, all Odyssey trims feature triple door seals and Active Noise Control technology to help prevent unwanted noise from reaching the passengers. While all trims benefit from thicker front and rear door glass, Elite receives acoustic front/rear door glass and adds an additional carpet barrier layer, acoustic fabric fender liners, additional slide door insulation, and rear wheelhouse insulators.
The new Odyssey greatly benefits from a much more rigid and tightly sealed body with substantially increased use of structural adhesives and sealers, as well as new front and rear suspension subframes and extensive aerodynamic tailoring to form the basis for a quiet vehicle. Additionally, the 2018 Odyssey uses a refined, multiple-tier insulation package that takes noise, vibration and harshness (NVH) countermeasures to the next level, positioning it at the top of its competitive set.
The new Odyssey makes widespread use of structural adhesives in the unit-body, supplementing structural welds and significantly increasing rigidity without the additional mass of steel components. Structural adhesives are used at the roof edges and around the moonroof opening, in the front floor and cowl area, in the A- and B-pillars, around the front suspension upper mounts, and extensively throughout the rear of the body. Applied before the body panels are welded together, some 147.6 feet of adhesives (32.8 ft. more than in the previous Odyssey generation) account for approximately 3.5 percent of the entire unit-body stiffness.
Located behind the instrument panel, the Honda Odyssey cast magnesium steering hanger beam replaces the multi-part steel unit in the previous Odyssey. Its purpose is as a structural attachment point for the steering column and instrument panel, as well as a structural element that helps the passenger cabin retain its shape in certain collisions. For the first time, the Odyssey body structure also utilizes composite materials to further reduce weight while enhancing rigidity and noise dampening. One example is inside the C-pillars, where composite stiffeners, together with the structural foam mentioned above help improve body rigidity. Another example is the base that supports the Odyssey battery. Created from a single composite casting, it holds the battery securely while adding minimal weight to the overall body structure, saving 2.9 lbs. over the previous Odyssey.
